Open Access Dissertations
In the fern Ceratopteris richardii, every spore has the potential to develop as either a male or hermaphroditic gametophyte. Gametophyte sex is determined by a GA-like pheromone (ACE) that is secreted by hermaphrodites approximately 6 days after spore inoculation and induces male development in other juvenile gametophytes. Our goal is to better understand the genetic and molecular mechanisms involved in sex determination and to identify sex determination genes in Ceratopteris. RNA-Seq was used to create de novotranscriptome assemblies from gametophytes grown, with or without ACE, during the time that their sex is determined, and from male gametophytes in early …
